I used a 68332 in a mobile robot a team of us built; we had timer channels to
spare and all the timing was done in the processor. That included all the
timing for ultrasonic sensors, infrared sensors, a digital compass and two
PWM motor drives. Heaps of grunt too, and the GNU compiler works a beaut.
